Given Input Data is 215, 731, 756, 641

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 215 is 5 x 43

Prime Factorization of 731 is 17 x 43

Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7

Prime Factorization of 641 is 641

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(215, 731) = 3655

GCD(215, 731) = ( 215 x 731 ) / 3655

GCD(215, 731) = 157165 / 3655

GCD(215, 731) = 43

Step2:

Here we consider the GCD from the above i.e. 43 as first number and the next as 756

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(43, 756) = 32508

GCD(43, 756) = ( 43 x 756 ) / 32508

GCD(43, 756) = 32508 / 32508

GCD(43, 756) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 215, 731, 756, 641 is 1
